Abstract (en)
[origin: WO2016007726A1] By either forming a triaryl acid halide or a triaryl mixed anhydride and subsequently treating with aqueous sodium azide, triaryl acyl azides are prepared in high yield using inexpensive reagents in a process in which by-products are easily removed from the triaryl acyl azide.
